Introverts are people whose
energy tends to expand through reflection and dwindle during interaction

Carl Jung, introversion and extraversion refer to the direction of

Introversion is "the state of or tendency toward being wholly or predominantly concerned with and interested in one's own mental life".[4]
Introverts are people whose energy tends to expand through reflection and dwindle during interaction.[5] Introverts tend to be more reserved and less outspoken in groups. They often take pleasure in solitary activities such as reading, writing, using computers, hiking and fishing. The archetypal artist, writer, sculptor, engineer, composer, and inventor are all highly introverted. An introvert is likely to enjoy time spent alone and find less reward in time spent with large groups of people, though he or she may enjoy interactions with close friends. Trust is usually an issue of significance: a virtue of utmost importance to an introvert choosing a worthy companion.
They prefer to concentrate on a single activity at a time and like to observe situations before they participate, especially observed in developing children and adolescents.[6]
Introverts are easily overwhelmed by too much stimulation from social gatherings and engagement. They are more analytical before speaking.[7]
